中頻電爐在開爐前必需要對電氣設備、水冷卻系統、感應器銅管等進行檢查，只有在這幾個設備完好的情況下才能開爐，確保熱處理的安全性，否則禁止開爐;確定專門負責送電和開爐的人員，并且負責人員不得擅自離開崗位，工作期間必需對感應器和坩堝的外部情況進行監管，以防止有人在送電后觸碰感應器和電纜，影響中頻電爐的正常作業或發生安全意外。
Before opening the medium frequency electric furnace, it is necessary to inspect the electrical equipment, water cooling system, inductor copper pipes, etc. Only when these equipment are in good condition can the furnace be opened to ensure the safety of heat treatment, otherwise it is prohibited to open the furnace; Determine the personnel responsible for power transmission and furnace operation, and the responsible personnel shall not leave their positions without authorization. During the work period, it is necessary to supervise the external conditions of the sensors and crucibles to prevent anyone from touching the sensors and cables after power transmission, affecting the normal operation of the medium frequency electric furnace or causing safety accidents.
2、開爐后的注意事項
2. Precautions after opening the furnace
中頻電爐開爐后，在進行裝料時，應對爐料內進行檢查，避免混入易燃易爆等有害物品。為了防止結蓋現象的出現，嚴禁在鋼液中直接加入冷料和濕料，以及在熔化液充滿到上部后不得加入體積較大的塊料;為避免出現爆炸意外，必需確保澆注場地和爐前地坑無積水，無障礙物;而在進行澆注時需兩人配合進行，而剩余的鋼液只能倒在在制定地點，不能隨處亂倒。
After the medium frequency electric furnace is turned on, during charging, the furnace material should be inspected to avoid mixing with flammable and explosive substances. In order to prevent the occurrence of capping, it is strictly prohibited to directly add cold and wet materials to the molten steel, as well as not to add larger bulk materials after the molten liquid is filled to the upper part; To avoid explosion accidents, it is necessary to ensure that the pouring site and the pit in front of the furnace are free of accumulated water and obstacles; During pouring, two people need to cooperate, and the remaining steel liquid can only be poured at the designated location and cannot be poured randomly.
